Itis also a great advertisement medium that not only promotes things butalso offers a night light for illumination.

In a preferred embodiment, the current invention can take the form of aplug-in wall outlet LED night light having projection features toproject the image, message, data, logo, and/or time on a ceiling, walls,or floor, or any other desired surface.

The night light of the current invention has as a light source an LED orLEDs, which may be the same as described in copending U.S. patentapplication Ser. No. 11/255,981 (now allowed) to provide a visible lightbeam that passes through an optics means or more than one optics means(as described in copending U.S. patent application Ser. No. 11/806,284)and creates an image at the desired location, preferably with one ormore features selected from group including size, dimension, area,height, distance, color, brightness, time period, and trigger means.

The current invention preferably incorporates optics means such as anoptics-lens or concave lens, and/or a telescope construction, openings,cut-outs, plastic parts, and a housing-member to create the preferredimage at the desired location to enable the viewer to see the image andalso offer illumination for a dark environment.

The current invention can also have a different construction whichenables a person to change the slides by a roller or push button orother mechanical means. This will enable one night light to exhibit aplurality of different images that can be selected to project on thedesired location

The current invention also may utilize an optics-means havingadjust-means to adjust the optics-means at any time and change theposition of the image to any desired location by a tilt, rotating, orswivel mechanism, or adjustment-facilitating other construction.

The current invention may also enable a focus of the image to beadjusted by providing an extend-means that causes a housing-member toextend and change the position of a slide, light source, and/or lens.

The current invention may furthermore use a very simple telescopeconstruction to enable the projection-means to be easily assembled intoa related housing-member to become a finished LED projection nightlight.

The current invention utilizes physics or optics lens theory to causethe projected image to have a desired size, clearance, details,brightness, or other image specification.

In addition, the current invention may use the “sealed-unit” describedin several of the Inventor's above-cited U.S. patent applications. Thesealed unit encloses all electric components, including a prong,circuit, trigger means, and/or an LED or LED connector, and seals theelectric components within the “sealed unit” to provide a safe AC powersource to turn on and turn off the said LEDs. The “sealed-unit” also canbe replaced by a battery-pack which has all electric components within,including batteries, circuitry, trigger means, and/or an LED or LEDconnector within to cause the night light to illuminate according to apre-determined function, timing, duration, and/or effects. Thisinterchangeable battery-pack and sealed-unit of the night light enablesthe “power source” to be changed from AC to DC or DC to AC.

Finally, the current invention can combine the arrangements disclosed inthe inventor's copending U.S. patent application Ser. Nos. 11/255,981and 11/806,284 for more than one light source and more than one ofoptics means with the arrangement described in the inventor's U.S. Pat.No. 5,667,736 for a grating or hologram to create a variety of differentimages and obtain an optimal image projection on the wall, ceiling, orfloor, as required.

DETAIL DESCRIPTION OF THE PREFERRED EMBODIMENTS

The LED night light with projection features of the current invention isdifferent from a conventional projection pen, projection key chain,projection toy, or commercial presentation projection equipment. Onedifference is that it is used mainly for night light applications withan LED or LEDs as a light source to directly plug into an outlet device,and as a result the circuit needs to be specially designed to make useof AC 110V 60 Hz input power to drive the LED or LEDs.

The current invention incorporates optics-means, which may include anoptics-lens, slides, openings, cut-outs, a transparent material piece, atranslucent material piece, a telescope assembly, a housing-member, aslide-disc, roller-means, an elastic-member, tilt-means, rotating-means,adjust-means, roller-means, mechanical-means, extend-means, a convexlens, a concave lens, and other elements calculated and designed to makethe image, message, logo, characters, sign, time, and data project ontoa desired surface such as a ceiling, walls, floor, or any other desiredlocation.

The current invention also may provide a geometric design for the wholenight light, and is not limited to the preferred embodiments. Analternative construction for the night light, for example with differenttilt, swivel, rotating, projection-position-change, focus-adjustablemeans, and/or slide-change features should still fall within the scopeof the current invention.

As shown in FIG. 1, a preferred LED projection night light (1) has atelescope assembly (1 b) that fits within a body with a top opening (1e) to project the image to a top area to form an image having a certainsize (1 g) at a certain distance from the opening (1 e). The night lightbody has a built-in mechanism or mechanical-means for installing aroller-means (1 c) with a plurality of slides (1 d) (1 d′) (1 d″) sothat people can change slides at any time and project different imageson the area (1 g).

As shown in FIG. 1A, the telescope-assembly has a housing-member (1-1)with an object-end (1-2) and eye-piece (1-3) having a preferred opticslens (1-5), lens (1-7), and slide (1-6) for each end. The lens (1-7) andslide (1-6) can have different positions as illustrated for differentimage requirements. The convex lens of arrangement (A) faces inside tomake incoming LED light beams into parallel light beams as they hit theslide so the image will be very clear. The arrangements (B) or (C) donot affect the image as much but are not clear as arrangement (A). Itwill be appreciated that alternative arrangements for thetelescope-assembly will still fall within the scope of the currentinvention. These may utilize the alternative constructions illustratedin FIG. 9A. The optics lens, telescope length, lens diameter, and/orfocus can all be well designed to get a desired image quality and sizeout of the LED projection night light.

As shown in FIG. 1B, the roller-means has a base (1-10) which hascertain holes (1-11) (1-11′) (1-11″) and poles (1-12) (1-13) to hold theplurality slides in position and also receive incoming LED light beamsso that they hit one of the slides to project colorful images on theslide to a desired location at a certain distance. Some applications donot need the roller-means for a plurality of slides. So long as theslide-film has fixing-holes, there is no need for any roller-means tohelp hold the slide-film. The current embodiment, however, lets peoplerotate the roller-means in order to enable people handle and changeslides.

FIG. 2 illustrates a plug-in LED night light (2 a) with projectionfeatures. At least one LED (not shown) serves as a light source tosupply visible light beams. At least one of the telescoping optics-means(2 d) incorporates an LED or LEDs, slide(s)-film (2 i), film, openings(2 e), cut-outs (2 f), a transparent material piece (2 m), translucentmaterial, grating means, and/or hologram means to project a desiredimage, message, data, logo, or time on a ceiling, walls, floor, or otherdesired surface. At least one of a power source (2 b), circuit means(inside of 2 a), and trigger means (2 c) are arranged to work with theLED or LEDs to provide a desired light function, timing, colors,brightness, and/or illumination. The LED projection night light device(2 a) has a changeable slide (2 i), film, angle, projection position,orientation, light functions, and/or light effects features.

As shown in FIG. 2, the current invention may also use the “sealed-unit”described in the U.S. patent applications of the inventor that arelisted below. The “sealed unit” contains all electric componentsincluding for example a prong, circuit, trigger means, and LED or LEDconnector, which are sealed within to safely enable an AC power sourceto turn on and turn off the LEDs. The “sealed-unit” also can be replacedby a battery-pack which has all electric components within, includingbatteries, circuit, trigger means, LED or LED connectors, to cause thenight light to illuminate and exhibit a predetermined function, timing,duration, and/or effects. The “sealed unit” is described in detail inthe following U.S. patent applications, which are herein incorporated byreference:

-   (1) U.S. patent application Ser. No. 11/527,631 (“LED Night light    with interchangeable display unit”).-   (2) U.S. patent application Ser. No. 11/498,881 (“Poly Night    light”).-   (3) U.S. patent application Ser. No. 11/255,981 (“Multiple light    source Night Light”).-   (4) U.S. patent application Ser. No. 11/094,215 (“LED Night light    with Liquid optics medium”).

The LED light of this embodiment includes a base having an empty innerspace arranged to receive a “sealed unit” of the type disclosed in theabove-listed applications with the above discussed circuit-means,sensor-means, switch-means, timer-means, IC-means, prong-means etc.

The “sealed-unit” with its own power, LED, circuit-means, and attachmentmeans is arranged so that it can fit into any LED light housing as longas the housing has a uniform compartment. The “AC powered sealed unit”is arranged to be connected to a 110Volt 60 Hz or other high voltageconnection while meeting all safety standards to make sure that thenight light does not present any hazard, risk of electrical shortcircuit, or potential damage by being subjected to multiple testingstandards and procedures for related safety certification.

The uniform compartment in the LED light housing is constructed and hasdimensions so it is easy to design the “sealed-unit” to fit into thiscompartment. The current invention also provides a “DC battery-pack”which has its own outside dimension similar to that of the “sealed unit”so that it can fit into the “uniform compartment” too. The “DC poweredbattery-pack” can replace the “AC powered sealed-unit” at any timebecause both have their own power, LEDs, circuit-means, and attachmentmeans that enable it to fit the same LED light housing as long as therehave uniform compartment.

As a result, the LED light of the illustrated embodiment can change itspower source from AC to DC or DC to AC. This is a further improvementover the “AC power sealed-unit” above-listed patent applications of theinventor. This is big improvement that not only saves a lot of toolingfor different shape LED lights but also saves a lot of safety testinglaboratory expense and time. Furthermore, the interchangeable powersource also can save a lot of tooling cost and time and labor and stillprovide a good LED light having a pinhole-imaging function (or other LEDlighting fixture, laser LED light device, etc.) with a same nice shapebut with different power sources to enable the light to be put indifferent locations where people stay. This is one of the big featuresof the current invention. Not only all different shapes of LED nightlight, but also a traditional puck light, can be powered by a DC batteryand also by AC as long as people pay for extra parts that let thetraditional puck light be plugged into an AC outlet.

As shown in FIG. 2, the LED night light (2 a) has a base with prong (2b), sensor (2 c), and a preferred circuit inside the base to turn on theLED or LEDs to supply a light beam that projects an image on theslide(s)(2 i) to the top ceiling. The night light has a top lens (2 m)having an opening (2 e) to allow the telescope optics-means (2 d) lens(2 k) to be installed and project the image to the top ceiling. The toplens (2 m) also has a cut-out (2 f) to allow the rotatable slide-disc (2g) to be installed and the slides (2 i) to be changed by rotating theslide-disc (2 g) to one of a plurality of the slides (2 i).

FIG. 3 shows more details of the construction of the embodiment of FIG.2. As described above, this embodiment includes a prong (3 b) on thenight light (3 a) with a top lens (3 e) having a top opening (3 c) toallow the telescope optics-means (3 m) to be installed and the image tobe projected through the top optics-lens (3 d) to the ceiling. Therotatable slide-disc (3 g) has a plurality of slides (3 k) (3 k′) (3 k″)securely installed on the discs (3 i) (3 i′) (3 i″) so that rotation ofthe disc (3 g) enables a user to easily change the slide and project thepreferred image on the ceiling. The top lens (3 e) has a cut-out (3 f)to allow the rotating slide-disc to be properly installed.

FIG. 4 illustrates another embodiment of a plug-in LED night light (4 a)with projection features. At least one LED (4 d) serves as a lightsource to supply visible light beams. At least one telescopeoptics-means (4 c) is incorporated with the LED (4 d) or LEDs orslide(s) (not shown), film, openings (4 e), cut-outs, a transparentmaterial piece, a translucent material piece (ball), grating means,and/or hologram means to project the desired image, message, data, logo,or time on the ceiling, walls, floor, a desired surface, or the opticsmeans surface. At least one of the power source (not shown), circuit (4b)(4 f) (4 g) (4 h) (4 i), and trigger means (not shown) is arranged towork with the LED (4 d) or LEDs to provide a desired light function,timing, colors, brightness, and/or illumination. The LED projectionnight light device (4 a) has a changeable slide, film, angle (forexample, if a ball is provided as shown, the ball can rotate), position(again, the ball can rotate), orientation (the ball can rotate), lightfunctions, and light effects features.

As shown in FIG. 4, the plug-in night light (4 a) has a power source andcircuit (4 b) inside the base, with conductive means (4 f) (4 g)(4 h)(4i) to deliver electric signals to the LED (4 d) to supply a light ofsufficient brightness into the telescope optics-means and its slides (4c) to allow the slide image to be project to the top through the opening(4 e) of the ball housing. The ball housing has a rotatable electricconnector (4 g) (4 h) and (4 g′) (4 h′) to allow electric signals to bedelivered from the base to inside the ball. It also offers a rotatingproperty to allow the ball housing to be rotated so as to make thetelescope project the image to a desired location, surface, or areas.

FIG. 5 shows a more simple construction. The plug-in night light withprojection features (5 a) of FIG. 5 has a power source input from theprong (5 b) through the inner circuit (not shown) and conductive means(5 f) (5 f′) to the inner LED or LEDs in order to supply a super brightlight beam to project the slide's image to the top area. In addition,the embodiment of FIG. 5 utilizes a “sealed-unit” which contains allelectric components including a prong, circuit, trigger means, LED orLED connector, as described above, in order to obtain power from an ACpower source to turn on and turn off the LEDs. The “sealed-unit” alsocan be replaced by a battery-pack which has all electric componentswithin, including batteries, a circuit, trigger means, an LED, and/orLED connectors, to provide night light illumination according to apre-determined function, timing, duration, and effects.

FIG. 5A shows a preferred embodiment (5), including details ofmechanical-means to allow people to change the slide (5-2) (5-10) bypush-button (5-5). The mechanical-means enables slides (5-2) (5-10) in aslide-film to fit into the center pole (5-30) and some side-poles (FIGS.5-3, 5-3 f and 5-3 f′) so as to hold the slide-film in position verytightly. The slide-film also has holes (not shown) to connect with thepole-disc (5-4) and the top of the pole-disc has several equally spacedbars which are pushed by a push-means into a certain space to preciselyposition the next slide at a position that allows the LED light beams tointersect the slide at a correct orientation and project the slide'simage to the desired location. The pole-disc (5-4) and its poles (5-11)(5-11′) are pushed by the push means (5-8) (5-9). The push-means (5-8)has a very big contact surface to make sure the force can been appliedto the pole (5-11) so as to move the pole a certain distance to allow anext slide move to a correct position relative to the LED light beam.The push-means (5-9) has more of a catching purpose to make sure thepole (5-11′) moves a certain distance and is locked in position. Hence,the push-means (5-8) (5-9) set enables a slide and a next slide to movevery precisely into position. A resilient-means (5-16) is situatedwithin the holder (5-18) and the holder has a stopper (5-3) to preventthe resilient-means (5-16) from falling apart and also offer a wall tolet the push-button (5-5) move back and forth to change a slide at anytime. A press means has two decorative parts (5-1) (5-1′) andholding-parts (5-12) (5-12′) to hold all other parts in position withoutfalling apart because of the resilient-means (5-16).

FIG. 5B shows another viewing angle for the push-button construction ofFIG. 5-1. The push-button (5K) is pushed by the resilient-means (Si) tocause the hold-bar (5 j) to also move down. The resilient-means (Si)will hit the stopper-means (5 g) and return it to its original positionafter the pushing force is removed from the push-button (5 k). At thesame time, the push-means (5 e) (5 f) moves down to push the pole-disc'spoles and move the next slide to a correct position. A press-means hasdecorative parts (5 b) (5 b′) and hold-parts (5 d) (5 d′) to hold allparts tightly in position.

FIG. 5C shows a slide-film (5-3W) having a plurality of slides (5-3 d)(5-3 d′) (5-3 d″) (5-3 d′″) (5-3 d″) (5-3 g) equally spaced on theslide-film. The slide-film has a plurality of positioning poles, and acenter hole (5-3 i) to position the pole (5-3 j). The two sides haveanother two positioning holes (5-3 e) (5-3 e′) to position the poles(5-3 f) (5-3 f′) and make sure the slide-film with its plurality ofslides is situated at a proper position.

FIGS. 5D, 5E, 5F, and 5G illustrate further details of the embodiment ofFIGS. 5-1 and 5-2 at different viewing angles and with different detailsfor each part. Details that have already been discussed will not bediscussed again. However, the larger illustration and drawing may behelpful in further clarifying the details discussed above. It will beappreciated that the current preferred embodiment involves a particularmechanical-means to change slide position, but that all other equivalentor same functions, and/or alternative construction, skills,arrangements, and methods of changing the slide position may still fallwithin the scope of the current invention.

FIG. 6 shows a telescope means (60 c) and optics-lens assembly (60 d)inside two half housings (60 a) (60 b). The two halves of the housing(60 a) (60 b) are assembled together by screws extending through thepoles (60 j′) (60 j) and holders (60 i) (60 k).

FIG. 7 illustrates details of a telescope (70) with a top portion (71)having a convex lens (78) inside. The other end (72) of the telescope(70) has a film (not shown) and convex lens (not shown) that areclipped-tight in location to make a tiny image on the slide become alarge image on the top of the telescope. The end (72) is inserted intothe receiving end (73) so that an LED light beam can be input to thetelescope to make the image project to a desired surface. The LED (74)is installed on an inner circuit-means and connected with a preferredpower source from an outlet or batteries (separate power source) tocause the LED to turn on with a predetermined time, function, duration,and effects.

FIG. 8 shows a detailed construction of a telescope (87) which has a topcover (80) to hold the convex lens (81) in position. The other end oftelescope (87) has two grooves (85) (86) to hold the slide's twoextended-ends (85 a) (86 a) and thereby hold the slide in positionwithout any deviation. The small convex-lens (84) is clipped-tight onthe telescope. The image seen from the small end of the telescope is atiny image (89) but the image seen from the front of the telescope is avery large image (88) because the telescope enlarges the tiny image to abigger size.

FIG. 9A shows an alternative telescope-assembly that can also be used toobtain a desired image.

FIG. 9 shows one of the considerations in enabling an LED projectionnight light for indoor applications to project images on a ceiling bytilting the optics means to more the image away from the wall andproject 100% of the image at the ceiling.

FIGS. 10-12 illustrate basic optic lens theory, which is applied to thecurrent invention to precisely calculate the optics lens, focus,position of the light source, position of all lenses, position of theslides, and/or telescope length to get a desire image that is as perfectas possible.

Although preferred embodiments of the invention have been described indetail to show the scope of the current invention, it is to beappreciated that any alternative or equivalent functions, or design,construction, modification, and/or up-grade, may still fall within thescope of the invention, which is not limited by the details mentioned inthe above discussion. Any alternative or equivalent arrangement,process, installation or the like may still fall within the scope of thecurrent invention, including alternatives to the power source,conductive means, geometric shape of LED-units, joint-means, circuitmeans, sensor means, switch means, LED elements, attachment means,fixing-means, tightening means, and/or resilient conductive means, whichmay all have alternative arrangements, design, and construction.
